Thanks. But again, the question is *NOT* about the terminology or the general meaning or definition of the categories. The question is specifically asking which authentication mechanisms Postfix places in those categories. > For more info I suggest a web search engine. If I could find the answer, I wouldn't need to ask the question. And frankly, it doesn't matter what might be written elsewhere (which may or may not be correct). All that matters is what is actually implemented in Postfix, i.e. which mechanisms are effected by the various smtpd_sasl_security_options categories. Does anyone here know which mechanisms are effected by noactive, nodictionary, forward_secrecy and mutual_auth? Or does everyone stick with "noanonymous, noplaintext". Thanks, Michael
